Trees are the most important part of our environment. They are having a direct impact on our lives. We can’t breathe except the existence of trees in the world. They leave the most important thing oxygen for us. But it is a matter of sorrow that day by day, the tendency of deforestation has been increased in the peak. It has been a matter of afraid now.
Due to the high tendency of deforestation, the world is lacking enough amount of oxygen. We need to plant more and more trees to make it normal. We have seen lots of examples that the world will face a hard time except for the existence of trees. Already, lots of species of trees have been extinct.
To fight against all the environmental odds, we need to grow more trees. The best time of growing trees is the rainy season. The soil has the best capacity to grow trees in this season. Trees have lots of uses for our regular life. We can make money and maintain our life with it. It is the biggest source of food.
If you plant lots of fruit trees, you can make a business on it. From today, we all need to start planting more and more trees.

- \' is used to escape a single quote in a string enclosed in single quotes like;
my_string = 'this is John\'s ball'.
- \n is used to jump to a new line, Eg;
my_string = "Johns is a good boy\nbut he hates going to school."
the next set of the string after the '\n' character is displayed on the next line.
- \t is used to add a tab space to a string.
my_string = 'Jane is \thungry'
the character adds four character spaces before the word 'hungry'.

my_string = "Johns is a good boy\rbut he hates going to school."

Answer:
The program displays 5 4 3 2 1 and then raises an Array Index Out Of Bounds Exception.
Explanation:
A sample of code output is attached.
The code snippet contain xMethod that takes an array and array length as argument.
In the given snippet, the array {1, 2, 3, 4, 5} and length (5) is passed as argument to the method.
First the method display the element of the array in reverse order
System.out.print(" " + x[length - 1]);
and then the method call itself again. This displays
5 from x[4]
4 from x[3]
3 from x[2]
2 from x[1]
1 from x[0]
but after displaying 1, when it tries to call the method again, an array index out of bound exception is thrown because it will try accessing an element from the array when it is already exhausted.
